Silistria (Crimean War).
This fortress was besieged by the Russians in 1854, and was defended by a Turkish garrison, who received valuable assistance from two English officers, Captain Buller and Lieutenant Nasmyth. Many attempts to storm the place were repulsed, and though no efforts were made to relieve them, the garrison held out until June 22, when the Russians raised the siege, having suffered a loss of over 12,000 men.
